PS814 1 in Dia. 10deg Beam Deviation; Round Wedge Prism Uncoated

The PS814 is a round wedge prism from Thorlabs, designed with a 1-inch diameter and a 10-degree beam deviation. This uncoated prism is made of n-BK7 Schott glass, a popular material in optical systems due to its excellent homogeneity and low optical dispersion.

The prism's geometry is meticulously crafted, with a thickness of 11.33 mm and a wedge angle of approximately 0.3168 degrees. The thickness at the edge is 3 mm, providing a robust structure while maintaining a manageable weight. The deviation angle is 0.1745 degrees, which is crucial for controlling the path of light in various optical setups.

The prism's shape is another notable feature. As a wedge prism, it is designed to refract and deviate light by a fixed angle, making it ideal for applications such as beam steering, beam expansion, and image rotation. The round base shape adds to its versatility, allowing it to be used in a wide range of optical systems.

Notably, the prism is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be advantageous in certain applications where the natural properties of the glass are desired, or where additional coatings might introduce unwanted reflections or dispersion.
